Bismaleimide monomers with various structures and polyaspartimides

A series of bismaleimide monomers with various structures were synthesized by the reaction of bisphenols or diamines with 3 or 4- maleimidobenzoyl chloride. The reaction of these bismaleimides with aromatic diamines (Michael addition) yielded polyaspartimides. The monomers and polymers were characterized by FTIR and 'H-NMR spectroscopy and elemental analysis. Thermal characterization of monomers and polymers was accomplished by differential scanning calorimetry and dynamic thermogravimetric analysis. Some of the mechanical properties of the films based on these polymers were studied.
